12 and 13 here, and my write up on the "Cheshire Cat outcrop," here, particularly clue #2. So that line of trees tells you that there's a bit more water in that portion of the cut than elsewhere, and that makes perfect sense. The lava, while jointed, is less permeable than the loose lahar deposits, so water tends to flow laterally along that contact until it reaches the surface, and signals its presence by supporting a stand of alders.
